One window and one door can turn a plain wall into several separate panel decisions. The casing interrupts the grid. A sill creates a horizontal stop. Door hardware moves through the space beside the wall. Before calculating quantity, draw the finished trim on a measured wall elevation and add a side view anywhere depth or clearance may matter.
Miami Walls does not currently publish a wall-panel listing or technical sheet. This guide creates a reliable opening record for a future product decision. It does not set a module size, cutting rule, edge treatment or installation method.
The wall-measurement guide explains how to record more than one height and width. Keep those full-wall measurements, then add the trim and opening details below.
Start with the finished trim, not the empty opening
Measure what you can see from the room. For a window, that usually includes the outside casing, inside reveal, sill and any apron below it. For a door, record both side casings, the head casing, threshold area and swing direction.
Use one reference corner and the finished floor for every location. Write the distance from that corner to the outside edge of the trim, then record the full trimmed width and height. Measure a window or door at more than one point if the gaps do not look equal. A photograph taken straight on helps later, but the written dimensions remain the record.
Add the baseboard and crown where they meet the casing. A stop line that looks clean in the middle of the wall may leave a narrow painted strip at the bottom or an awkward break at the top.
Give each opening its own card
Label the openings Window A, Door B and so on. One compact card prevents measurements from similar-looking openings being mixed together.
| Opening card field | What to record |
|---|---|
| Position | distance from the reference corner and finished floor |
| Finished trim | outside casing width and height, sill projection, apron and threshold |
| Depth | wall face to casing face, plus reveal depth where visible |
| Moving parts | door swing, handle, blinds, shutters and window operation |
| Nearby items | switch, outlet, vent, control or wall-mounted hardware |
| Normal views | what is visible from the doorway and the main seating position |
Take one straight-on photograph and one angled photograph from each side. The angled views show the casing projection and return edges that disappear from the elevation.
Draw two side views where the wall changes depth
An elevation shows width and height. It does not show whether the panel face would sit behind, flush with or in front of the casing. Draw a small side view at the window jamb and another at the door casing. Include the wall face, trim projection and the space used by moving hardware.
Leave the proposed panel thickness blank until the exact product document supplies it. Do the same for backing, mounting assembly and finishing profiles. When those dimensions become available, add them to the side view and check the relationship again.
Do not assume an unknown panel can continue into a window reveal or cover existing casing. Those choices may affect edge finishing and operation. The product instructions and the actual opening have to support the detail.
Test the grid with paper strips
The easiest way to see a bad edge piece is to make it visible before ordering. Cut paper strips to a convenient scale and lay them across the wall elevation. Mark the proposed joints, then slide the entire grid left or right.
Watch what happens on all four sides of the main opening. A centered window does not guarantee balanced pieces once the grid begins at a room corner. One shift may improve the left jamb but create a thin piece beside the door or under the sill.
Try a second version with the panel field stopping at an architectural line, such as the outside edge of the casing. View both drawings from the room entrance. The better plan is the one whose joints and stop lines look intentional across the whole wall, not only in a close-up of the window.
The paper test studies proportion. It does not authorize a cut. Final joints, usable face width, direction and permitted cuts must come from the selected system.
Check the moving parts while the layout is visible
Use painter's tape to mark the proposed panel boundary on the wall without attaching material. Open the door fully. Operate the window, blinds or shutters. Move the handle through its normal path and look at the taped edge from both adjoining spaces.
Record any conflict on the opening card instead of solving it with an assumed trim piece. Also mark outlets, switches and vents near the opening. Their covers and access may be affected by finished wall depth, which remains unknown until a real product and assembly are chosen.
Count product units only after the edge plan is approved
Subtracting the area of a door or window does not tell you how many sellable modules will be interrupted. Quantity depends on the confirmed grid, the product's dimensions, direction, joint and rules for offcuts.
The current Wall Panels World measuring page records wall dimensions at several points and treats doors and windows as separate measurements. Its percentage and subtraction rules apply to its own planning system. They are not Miami Walls quantity instructions. Keep the opening record, then use the exact seller's calculation method for the product under consideration.
The wall-panel buying guide lists the product documents that should exist before final quantity or installation decisions. A manufacturer library such as Wood Veneer Hub's Slatpanel page separates technical sheets by panel system. That separation is useful: one system's thickness, cut or mounting detail cannot be carried over to another.
Send one drawing with the unanswered product questions
Before ordering, the drawing should show the full wall, every opening card, the two depth views and the preferred paper-strip grid. Attach the straight-on and angled photographs. Then ask one direct question: "Which module dimensions, finished edges, allowable cuts and mounting build-up apply to this exact product?"
Keep claims about moisture, fire, emissions, acoustics or durability out of the plan unless the document names the selected panel and tested assembly. Miami Walls has not published those specifications for its planned category.
You can send the opening packet through the Miami Walls contact page. It gives the team a concrete wall to discuss while the product details and availability remain unconfirmed.
